AcnTYLnNE-GAS GENERATOR.

Application filed August 8, 1916. Serial No. 113,739.

To all whom t may] concern: Y y

Be it known that we, CLAYTONT. Cook and CHARLES B. Coon, citizens of the United States, residing at Owosso, in the county of Shiawassee and State of Michigan, rhave invented certain new and useful lmprovements inAcetylcne-Gas Generators,

vof which the following is a specification.

Uur invention relates to acetylene gas generators of the displacement type 1n which the increase of gas pressure tends to lift the carbid holder from the water and thereby automatically control the generationof gas in proportion to theV amount consumed.

@ne of the objects of our invention is to provide a generator which will not only automatically generatey the gas in accordance to the consumption but will also accurately Vregulate the pressure of gas in the supply pipe or gas main so that the pressure or flow at the burner will 'be uniform. A further object is to greatly simplify the construction of the generating apparatus.

into the water 3 in the tank and rises'vand` falls in Vaccordance with the `variations in the volume of gas, being guidedon the rods 5, secured to the sides and bottom lofthe Y tank, by the guide-members 6, securedto the bell.

The dip carbid-container or receptacle 3, is formed with aconical bottom provided the carbid 10, as the bell sinks. Thereceptacle is fastened in the' upper part of thebell in any suitable manner, as by chains 12, which may be looped or hooked to handles ,14 on the under side of the container.

When it is desired to charge the generator, after opening the air-cock 15 and removing the plug 16 from the air-vent 17, the bell is lifted from the well by means of the handles 19, and then inverted to give ready access to the carbid-receptacle. After unfastening the chains 12 the receptacle'S is lifted from the bell 2 by the handles 14, and after Specification of Eietters latent.'y Patent-,Qd Sept.` 192:0.

*PATENT .oflucaf'l ,being sued with carbid it isV placed in. the.

belland'secured by the chains. The bell is then lowered into-the well. The air vent 17 Y.is closed by the' plug 16, but the air-cock 15 1s left open until the airis drivenout'by the ,v

gas and is then closed. f

When the'bell is lowered into the well it.: i.

descends until the lower part" of the perforated conical bottom of thereceptacle 8 1s submerged but is quickly lifted by the pressure of the gas vwhichis immediately generated. Ass the carbid is gradually' consumed the bell sinks lowerand lower, `per- Amatting the lwater to yrise higher in the receptacle until all the gashas been liberated by the action of the water upon the carbid.,4

- For the purpose of overcoming the fluctuations in gas pressure at? the lburners we .provide a. pressure` regulator which main'- tains a substantially constant pressure yin the gas main 21.

The pressure regulator com-.

prises an outer inverted container 23: which lis loosely supported upon'a shelf 24, fastened to the pipe 25, t permit the water to rise in the. lower part ofthe container 23 suliicientlylto form a water seal.; 1A eylindrica'l ypocket or recess 27vinzthe carbid holder 8, permitsthe latter to move over the regulator as it rises or falls.V The gas-.regulator bell 30 Vcan vrise and fall within the container 23, the pressure requiredv to lift it being accurately adjusted by the weights 31 until the pressure is attained which it is desired .to maintain in the gasmain. The U-shape inlet pipe 34, by which the gas enters lthe bell 30, is rigidly fastenedby straps 35'to the inner-wall of the bell and is movedup and down therewith, being guided through Yopenings 36, `37 in the plate 24. j An extension 34 depends from the bend in the pipe 34` and forms -a closed trap for any moisturecar- ,y

ried by4 the gas.

mal pressure the bell descendsto the position shown in Fig. 1, and the gas within the main generating .bell 2, flows .through the -shaped -inlet pipe 34 untilthe gas pressure is lsuf- When the gas in the pres-v with vperforationsv 9, which admit water to vsure regulator bell 301is reduced below nor-A ing a number of sievesv oi' filters If at' any time thereis an accumulation of water l in the traps 25a, 25c and 34 the' main and pressure bells are removed ,after which the filter tube 40 may be lifted out and the pump 42, inserted, for example, into the pipe 25 until its lower end extends into the watertrap 25a. Upon lifting the pump plunger 43 the water will beV drawn into the pump cylinder. y

The operation of our apparatus will be understood from the foregoing detailed description. The gas will be generated in the main bell 2, as long asthere remains any uncombined carbid in the container, 8, the bell 2 gradually descending and-iinmersing the carbid container deeperV in the water in the well l, as the carbid is exhausted.

The pressure regulator bell 30 will contiiiually rise'and fall with the fluctuations in the gas main in accordance with the consumption at the burners, causing the open endof the inlet pipe 34 to engage or move Yaway from the closure pad 38 inA a manner yto keep vthe gas pressure in the bell 30 practically constant. The result of this automatic regulation of the gas pressure in the gas mains is to prevent any flickering at the burners and to maintain a Vsteady light.

We have described in detail the particular construction illustrated in the accompanying drawings for the purpose of clearly disclosing an embodiment of ourinvention but it will be evident to engineers that various changesv and modifications can be madeA therein within the scope vof our claims and without departing from our invention.

We claim- V1. In an acetylene gas generator, wherein a main gas bell carrying a perforated carbid receptacle; is movable vertically within a well or tank adapted to contain a supply of water and dipping into the water, and an outlet mainv or pipe extends into said bell the combinationl with said outlet main of a pressure regulator inclosing the mouth of said pipe within said main bell and comprising a vertically movable regulator bell, a supportV therefor below the level of the water in the main bell, an inlet pipe carried by said I regulator bell and connecting the interior thereof with that of the main bell, and a closure adapted to close the outer end of said inlet pipe when the regulator bell is .within said tank and dippinginto the water,

and an outlet main or pipe lextending into said bell, the combination with said outlet main of a pressure regulator surrounding the mouth of said pipe within said main bell and automatically controlling the gas pressure within said main, said regulator coniprising an outer inverted casing or shell having a closed upper end, a regulator bell vertically movable within said casingV and weighted to maintain a predetermined internal pressure, a support or platform upon which said casing and said regulator bell are held, an inlet tube connecting the n main gas bell with the interior of said regulator bell and secured to the latter to move.'

therewith, and a stop or closure carried by said'casing and adapted to close the outer end of said inlet tube when the regulator bell is in its uppermost position.

3. In an acetylene gas generator, a `well or tank adapted t0 contain a` supply vof water, a main gas bell carrying a perforated carbid Vreceptacle movable vertically within said tank and dipping into the water, an outlet main or pipe extending into said bell and having a water-drip portion extending below the Vwell of said tank to receive any water or moisture condensation in the pipe, and a pressure regulator comprising a small auxiliary bell vertically movable within the main gas bell, said auxiliary bell surrounding the mouth of the outlet pipe and automaticallyV controlling Vthe gas pressure inV said gas main.

In testimony whereof we affix our signatures in presence of two witnesses.
